You have this low-tech piece of equipment that brakes the non-drive wheels while spinning the drive wheels (called a "line lock"), problem solved. I guess they are going to do that, but with some electronics?
After switching to x86_64, the next big win, much more than microarchitectural optimizations (which are pretty minor), is to compile with profile-guided optimization (PGO). There's enough indirection in Firefox that some decent profiling data that lets the compiler reliably figure out which are the common cases really speeds things up. Unfortunately, most distros don't compile that way by default, because it doesn't fit well in the automated build process.
In the situations I've encountered turnaround time hasn't been the bottleneck keeping smaller businesses from automating things with robots. Maybe there are some cases where you really need custom stuff on the spot, but more often you can wait a week. The problem is that at small scale stuff is expensive and high-overhead. If you want one industrial robot, you are going to pay a lot for it, and you are going to incur a lot of labor costs just getting the thing to work.
I think it's also marketing aimed at recruitment to some extent. Amazon wants to be a cool tech company, like Google with their self-driving cars and whatnot. There's a danger they will become seen as just a boring logistics company, a profitable high-volume/low-margin business whose main technology is "warehouses". That's a successful business strategy (look at Wal-Mart), but not cool.
They used to be much more differentiated, but they're overlapping more and more. Traditionally eBay's business was regular people selling used stuff, while Amazon's was first-party sales by Amazon. But both of them now do a lot of business in the third category of being basically the storefront for third-party businesses selling stuff. Everything from camera shop like Adorama, to third-party bookstores, now list a ton of items through both eBay and Amazon Marketplace, which is where they compete most directly.
There's an odd preference for already-employed people, so there's this kind of self-reinforcing phenomenon where, if you already have a job, you can easily get five job offers, but if you have no job, you can't get any job offers. Especially true if you've been unemployed for a non-negligible period of time: 3 months or something is fine, looks like you're just between jobs, but 3 years and employers start to assume there must be some horrible dark reason, and pass on the resume. Basically a variety of "social proof".
I suspect this is large part because companies have no reliable way of actually interviewing or screening potential hires, so they rely on these kind of tea-leaf-reading heuristics instead. Some of it is also that large companies are mostly looking to avoid bad hires, versus to get good hires. They might be passing up a great hire, but what they really care about is not hiring anyone who will rock the boat and cause problems.
how is this company even got a voice in America? in the old days they would be run out of town or worse
Nah, in the old days people would've tried to run them out of town, but they would've hired some private thugs (Pinkertons, etc.) to run the other people out of town instead.
I wonder if this is really aimed at academia.edu rather than the authors. As far as I can tell, Elsevier hasn't (yet, at least) gone after academics posting their own papers on their own website in the traditional manner, i.e. as a PDF at www.university.edu/~jsmith/papers/smith2013bigresult.pdf.
you want to destroy a representation of the records, but keep them in storage somewhere?
I was more imagining the records fashioned into a Wicker Man style construction, with Clapper, Alexandar et al as the soft centre. I'd be tempted to do some chanting and dancing around that
That's 4.5 kilowatt-hours per day. I.e. in a day, it draws 4.5 kWh of energy.
A watt is a unit of power. A watt-hour is a unit of energy. 1 Wh = 1 W x 1 h. Similarly, 1 kWh = 1 kW x 1h. A 200-watt motor left on for an hour will draw 200 Wh of energy. A 200-watt motor left on all thetime will draw 200 W x 24 h = 4.8 kWh of energy per day.
